BICYC LE STAN D.

To all whom it may concern:

Be it known that I, ALBERT KRIMMERT, a citizen of the United States, and a resident of Brooklyn, county of Kings, and State of New York, have invented certain new and useful Improvements in Bicycle-Stands, of which the following is a specification.

This invention relates to a bicycle-stand which is so constructed that the bicycles are protected by an inclosing shell which may be readily raised,so that all the bicycles may be simultaneously exposed.

In the accompanying drawings, Figure l is a vertical central section, partlyin elevation, of myimproved bicycle-stand on line 1 1, Fig. 2. Fig. 2 is a horizontal section on line 2 2, Fig. 1. Fig. 3 is an enlarged horizontal section on line 3 3, Fig. l; and Fig. 4, a detail vertical section through part of the threaded sleeve and shaft.

The letter 0t represents the base of the stand, upon which is mounted a casing 19, containing an electromotor 0, controlled by the usual switch 0. From the casing 19 projects up wardly a fixed sleeve cl, which has an inner or female thread cl at its upper end, Fig. 4. This thread is engaged by a corresponding male thread formed on a hollow screw-shaft e, which is telescoped by sleeve d.

The shaft 6 supports at its upper end a roof f, which is shown to be connected to the shaft by the rafters f. From the roof f depends a cylindrical shell g, which is open at its lower end and is provided with a laterally-opening door g. The shaft 6 is adapted to be rotated from the motor 0 by means of a squared rod it, that is secured to the armature-shaft o of the motor and projects into the hollow of the shaft. The rod 72. engages a squared opening 6 of shaft 2 and terminates in a head It, that limits the upward movement of the shaft.

SPECIFICATION forming part of Letters Patent No. 668,259, dated February 19, 1901. Application filed November 16, 1900. berial No. 36,662. (No model.)

The sleeve (1 is provided with two or more offsets (1 adapted to support revoluble frames or brackets 2', that surround the sleeve. To each of the brackets t'are secured a number of radially-projecting forks 2'], which are ope-n at their outer end and from which the bicycles A are adapted to be suspended. Each of the forks may be provided with a lockcase 71 containing a bolt by which the bicycle may be locked to its support.

If it is desired to gain access to a single cycle, the bracket L is revolved until the fork 11 desired is in alinement with the door g. If it is desired to uncover all the forks simultaneously, so that all the cycles are accessible, switch 0 is closed to start the motor a and to thus rotate the squared rod h. This rod in turning will rotate the shaft 6, which will thus be screwed out of sleeve d and will raise the shell g above the upper row of forks i. If the current is turned off, the screw-shaft 6 will be caused to descend by the weight of the roof and shell.

What I claim is In a bicycle-stand, the combination of a fixed threaded sleeve with a series of radiallyprojecting forks supported thereby, a rotatable threaded hollow shaft engaging the sleeve and having a squared opening, a roof supported by the shaft, a squared headed rod entering the hollow shaft, and a motor adapted to rotate the rod, substantially as specified.

Signed by me at New York city, county and State of New York, this 9th day of November, 1900.

ALBERT KRIMMERT.
